Application'Octob'er 16, 1951, Serial No. 251,531

Claims; (CI. 20-65) Fig. 1. The back plate 4 is provided nearits centerwith a vertical slot 6, Fig. 4. Within the sectional casing 2a is asplit rotatable cylinder opens outwardly, or a door that opens inwardly.

A still further object of the invention is to produce an efficientdevice that will fit tightly the door and jamb, as well as sealing thedoor against drafts and other disagreeable conditions. Further, thisdevice will function'with or without a door-sill.

The invention of this application is an improvement upontheinventio-ndisclosed in my United States Patent N 0. 2,565,393, issued August 21,1951.

With the foregoing and other objects in view, this invention comprisescertain novel constructions, combinations, and arrangements of parts aswill be hereinafter fully described, illustrated in the accompanyingdrawings, and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a view in front elevation of a device constructed inaccordance with this invention, showing same applied to a door that isintended to swing inwardly.

Figure 2 is a fragmentary end view of a door frame and a (1001' to whichmy invention is applied.

Figure 3 is a view in end elevation of the device in a closed position.

Figure 4 is an enlarged sectional view, taken on line 4-4, Fig. 1, andlooking in the direction of the arrows.

Figure 5 is a view similar toFigure 1, showing a modified form of thedevice applied to a door that is adapted to swing outwardly.

Figure 6 is a View in end elevation, showing the door frame and doorwith my device applied thereto, in an open position.

Figure '7 is a view in end elevation, showing the device of Figure 6 ina closed position.

Referring to the drawings, in which the preferred specie of thisinvention is shown in Figures 1 to 4, I designates the door frame and 2the inwardly swinging door.

The device comprises a sectional casing 211 consisting of a cover plate3 and a back plate 4. These two plates are held together by screws 5,

or sleeve '1. This sleeve 1 is provided with a transverse slot 8. Acomparatively flat spring!) has its upper end in slot 6. -The lowerportion of spring 9 is in the slot 8 and presses against the lower endof the slot, as clearly shown in Fig. 4. An elongated-seal In is mountedon the split sleeve 1 and extends the entire length of said sleeve.spaced longitudinal grooves ma selectively engageable by one edge ofsaid'split. This structure permits adjustment of seal H] in and out ofthe sleeve '1. e

A nut I l is placed in the upper portion of slot 5, with the springsbearing against same. A

screw 5 extends through the upper portion ofthe cover plate 3 andthrough spring 9 and the nut ll, whereby the spring 9 i's-held in anexcellent position. I

The rotatable sleeve '1 is provided on its ends with lugs I2, which areadapted to engage adjustable screws 13. When the door 2 is moved to aclosed position, the lug I 2 comes in contact with the screw l3,resulting in the sleeve being rotated, from the position shown in Fig. 2to the closed or sealing position shown in Fig. 3. As

soon as the door is beginning to move to an open.

position, the spring 9 will begin to rotate the sleeve 1, whereupon theseal ID will begin to move upward until it is in its open position, asshown in Fig. 4.

The embodiment shown in Figures 5 to 7, is substantially the same withreference to the spring construction, as described for the embodiment ofFigures 1 to 4. In this embodiment, the lugs or triggers 12a are placedin a relatively higher position on the ends of the rotatable sleeve 1,and the screw l3a is also placed parallel on the door frame I so thatthe trigger or lug 12a will strike against the screw 13a, causing theseal ID to be moved to a closed or sealing position when the door isentirely closed. On the outer ends of the back plate 4a are formedrightangled brackets [4. These brackets l4 serve to hold the rotatablesleeve securely within the sectional casing.

One of the advantages of my construction is that the seal can be cut offat either end to fit a job, irrespective of the width of the door. Thiscan be more readily accomplished when using the seal device of Figures 1to 4.

While I have described the preferred embodiments of the invention andillustrated the same The seal l 0 is provided with transversely in theaccompanying drawings, certain minor changes or alterations may appearto one skilled in the art to which this invention relates during theextensive manufacture of the same, and I, therefore, reserve the rightto make such changes or alterations as shall fairly fall within thescope of the appended claims.

What I claim is:

1. In a device of the class described, the combination of a sectionalcasing comprising a cover plate and a back plate, said back plateprovided with a transverse slot, a, rotatable split sleeve in saidcasing, said sleeve provided with a slot registering with saidfirst-mentioned slot, a spring fastened to said casing and positioned insaid registering slots and exerting pressure at all times on saidsleeve, and said sleeve being provided with a seal, said seal consistingof an elongated strip extending through the split of the sleeve andprovided with transversely spaced longitudinal grooves selectivelyengageable by one edge of said split.

2. In a device of the class described, the combination of a casingprovided in its back with a vertical slot, a rotatable split sleeve insaid casing,

said sleeve provided with a slot registering with said first-mentionedslot, a spring fastened to said casing and positioned in saidregistering slots and exerting pressure at all times on said sleeve, andsaid sleeve being provided with a seal, said seal consisting of anelongated strip extending through the split of the sleeve and providedwith transversely spaced longitudinal grooves selectively engageable byone edge of said split.

3. In a device of the class described, the com-- bination of a casing, arotatable split sleeve within said casing, a spring mounted on saidcasing and extending into said sleeve, said spring at all times exertingpressure on said rotatable sleeve, and a seal carried by said rotatablesleeve, said seal consisting of an elongated strip extending through 4the split of the sleeve and provided with transversely spacedlongitudinal grooves selectively engageable by one edge of said split.

4. In a device of the class described, the combination of a sectionalcasing, a comparatively fiat spring secured between the sections of saidcasing, a rotatable split sleeve within said sectional casing, saidrotatable sleeve provided with a slot, said spring extending into saidslot and exerting continuous pressure upon said s1eeve,and a sealcarried by said sleeve, said seal consisting of an elongated stripextending through the split of the sleeve and provided with transverselyspaced longitudinal grooves selectively engageable by one edge of saidsplit.

5. In a device of the class described, the combination of a casingprovided with right-angled brackets extending from the back of saidcasing, a rotatable split sleeve within said casing, a spring carried bysaid casing and pressing continuously against said sleeve, and a sealcarried by said sleeve, said seal consisting of an elongated stripextending through the split of the sleeve and provided with transverselyspaced longitudinal grooves selectively engageable by one edge of saidsp it.
